What Are Central Silos?
Central silos are storage systems installed near your production area to hold raw plastic materials such as pellets, flakes, or regrind.
Unlike outdoor welded silos, indoor central silos use a modular, assembled structure — each panel is numbered and bolted together on-site for quick setup and easy transportation.
They are widely used in injection molding, extrusion, and blow molding factories that require reliable, space-saving, and automated material storage.

Why More Factories Choose Central Silos
1. Efficient Indoor Material Storage
Central silos can be installed inside the production workshop, minimizing conveying distance and ensuring stable material supply to machines.
2. Modular Assembly Design
Each panel is prefabricated and numbered. You can assemble the silo easily — just like building with LEGO blocks.
No welding or heavy cranes are needed, saving both installation cost and time.
3. Perfect Fit for Central Feeding Systems
Central silos are designed to integrate directly with central feeding systems, forming a fully automated material handling network.
This allows continuous, dust-free conveying of materials from silos to multiple processing machines.
4. Flexible Capacity and Expansion
The capacity of central silos can be customized according to your material type and production scale — from a few tons to dozens of tons.
When your business grows, you can expand by simply adding new modular sections.
Typical Applications
- Indoor material storage for injection molding, film blowing, blow molding or extrusion plants
- Mixing and distribution center in a central feeding system
- Storage for multiple resin types and additive
- Factories with height or space limits where welded silos are impractical
Example – Central Silos in a Plastic Sheet Factory
A PET sheet extrusion factory faced limited ceiling height (4.5 meters).
Using assembled central silos, they installed six indoor units, each 5 tons, connected directly to the central conveying system.
Result: material logistics became fully automated, installation finished within three days, and floor space was optimized by 30%.

FAQ About Central Silos
Q1: What is the difference between central silos and traditional silos?
A: Central silos are modular and can be installed indoors, while traditional welded silos are fixed and usually placed outdoors.
Q2: Are they easy to install? Can we assemble them ourselves?
A: Yes, very easy. Each panel has a serial number — you can assemble it step by step like LEGO. We also offer remote guidance if needed.
Q3: Can central silos connect with our existing feeding system?
A: Absolutely. The outlet size and angle can be customized to match your current central conveying pipeline.
Q4: How long does installation take?
A: Normally 1–3 days per silo, depending on its size and site conditions.
From Central Silos to Central Feeding System
Once central silos are installed, they become the core of your central feeding system.
The silos store materials, the central conveying system distributes them automatically, and the gravimetric blender ensures precise mixing.
Together, they create a smart material handling network that minimizes labor and production errors.
